Q:Is the coil strip? Is hot rolled coil and hot rolled strip the same?
As for the "Q235" mentioned below, this steel can not be deformed under the pressure of 235 MPa and is used to represent the material of steel. Similarly, Q195 is naturally deformed at 195 MPa pressure.
Q:What are the categories of strip steel? How do you distinguish it?
Steel is divided into two major categories: carbon steel (carbon steel) and alloy steel by chemical composition. Carbon steel is an alloy obtained by smelting pig iron. Besides iron and carbon, it also contains a small amount of impurities such as manganese, silicon, sulfur and phosphorus. Carbon steel has a certain mechanical properties, but also has good technical performance, and low prices. Therefore, carbon steels have been widely used. But with the rapid development of modern industry and science and technology, the performance of carbon steel has not fully meet the needs, so people have developed a variety of alloy steel. Alloy steel is a multicomponent alloy obtained by adding certain elements (called alloy elements) on the basis of carbon steel. Compared with carbon steel, the properties of alloy steel have been improved greatly, so it has been widely used.
Q:What is the cause of the deviation of the strip in the rolling process? How to deal with it?
Because of the sudden decrease or disappearance of the tension of coiler during the rolling process, the strip is running off and breaking.
Q:Why is strip heat cheap?
Coil is 800mm in width, material better than the strip, because hot rolled production to refining furnace.
Q:What are the raw materials for making strip steel?
Cable for cold rolled strip using B2F and BY2F steel as the material used for the steel base material of galvanized or other coating strip manufacturing armoured cable
Q:What's the reason for the strip after pickling?
Will it use a strong acid wash, and the temperature is too high to destroy the ductility of steel?.
Q:What is the meaning of C hot strip material, B material is how to distinguish between
Hot rolled steel plate surface is plated black brown, plating cold rolled plate surface is gray, after plating from the surface smoothness to distinguish, lengzha board smoothness is higher than that of hot rolled steel plate.
Q:Reasons for black side of hot strip galvanizing
The content of zinc chloride in plating bath is too low, which leads to some parts can not be plated and lead to local blackening.
Q:Specification and use of cold rolled strip
Advantages of cold rolled strip:A very thin strip of steel (0.001mm), which is difficult to obtain by hot rolling method, can be obtained;It can make the product have high mechanical properties and wide range of performance;Guarantee to obtain the high precision size, the thickness deviation is small, along the strip width and the length aspect uniformity, the shape is good, the surface is bright and clean each kind of strip steel;Low cost and high efficiency;Rolling speed, with high productivity.Technological characteristics of cold rolled strip:When the strip is rolled in cold condition, because of the hardening of the strip, the intermediate annealing must be done to soften it and restore the plasticity so as to continue rolling;The surface iron oxide scales must be removed before rolling, thus ensuring the surface smoothness of the strip and reducing the wear of the roll;Adopting tension rolling to ensure good strip shape of strip, controlling the deviation of strip thickness and reducing rolling pressure, which is beneficial to rolling thin specification products.Using process cooling and lubrication, it is easy to control the temperature of roller and strip, reduce the friction between roll and strip, and reduce the rolling pressure. It is favorable to shape control and prevent the sticking roll of strip steel.
Q:Can the tension leveller eliminate the wave shape of strip steel completely?
We take the longest and shortest fibers in the cross section of the strip and analyze their elastic and plastic deformations under the action of tension. In addition to external force because of tension by strip in straightening process, and bending stress and bending stress is tensile stress and compressive stress of the component, and the main role is tensile stress, the main deformation so through the analysis of tensile deformation on behalf of strip.
